Specification of Letters Patent.

Patented Apr. 2, 19118..

Application filed November 2, 1916. Serial No. 129,207.

To all whom it may concern:

Be it known that I, FRED MAKI, a citizen of Finland, and a. subject of Russia, residing at Portland, in the county of Multnomah, State of Oregon, have invented certain new and useful Improvements in Devices for Use in Splicing Ropes or Cables, of which the following is a description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to a device for use in splicing ropes or cables and more particularly to .a power operated marline spike adapted especially for use on large ropes or cables. r The object in view is to provide a simple, durable and inexpensive device of the class described possessing features which are adapted especially for the splicing of heavy cable, where the ordinary hand operated marline spike would be ineffectual, said device being a conveniently portable appara tus, by means of which the strands of the cable may be lifted and the interlacing strand readily inserted beneath, said lifting ofthe strand by the insertion of the marline spike being accomplished by highly powerful means, which said means for inserting the marline spike being useful when reversed to withdraw samefrom beneath the strand. i

A practical embodiment of the invention is represented in the accompanying drawings forming part of this'specification in which similar reference characters indicate corresponding parts in all the views.

Figure 1 is a perspective view of the device shown with the parts in active position and the nose of the marline spike inserted beneath a strand of cable.

Fig. 2 is a vertical longitudinal section of the parts as shown in Fig. 1.

Fig. 3 is a transverse section.

Reference being now had to the drawings by numerals, 1 represents approximately parallel side braces provided at one end with hooks 22 and at their other ends with inturned portions 3-3, which are riveted, as shown at 4, to the cross head 5 permanently secured between said side braces. A guide brace 6 is rigidly mounted midway the ends of the side braces, and between said braces, a screw-threaded shank 7 mounted at one end in the guide brace 6 and at its other end in the cross head 5 is provided with the squared end portion, as shown at 8, on which is mounted the crank shank.

Mounted to slide on the side braces between the guide brace and the cross head is a traveler head 10, said traveler head being provided with a screw-threaded aperture adapted to receive the shank 7 and as said shank is turned, said traveler is adapted to be operated. An aperture 11 is providedin the guide brace 6 and an aperture 12 is provided in thetra-veler head 10, said aperture 12 receiving one end of the marline spike shaft which is firmly secured therein by lock screw 13. Said marline spike shank 14 passes through the aperture 11 in the guide brace 6 and is adapted to slide freely in said aperture.

The marline spike 15 may be of any preferred shape or size having a reduced forward end, as shown at 16, adapted to be forced beneath the strand of a cable to lift same free of the other strands in such a position as to permit the insertion of the end of a strand beneath it. Said spike is then withdrawn and the operation is repeated me well known manner to complete the. splice.

As shown in the drawings, it will. be clear that the hook members 2 receive the cable and resist the thrust of the spike as it is forced under the strand of the cable to be lifted. A swinging member 17 mounted for pivotal movement at 18 may be swung into the position shown in dotted lines in Fig. 1, which will firmly hold the cable during the forward movement of the spike and also when the spike is being withdrawn.

A handle 19 is mounted on a swinging bail 9 adapted to operate the 20 secured to the side braces to facilitate the operation of the device and maintain it in its proper position when the crank is being operated.

It will be readily appreciated by one familiar with the art of splicing that after the serving wire, as shown at 21 in Fig. 1, has been applied to the cable, said cable being of heavy weight, it is a very difficult matter to force the marline spike beneath the strands especially so in the first lacing operation for the reason that said strand is held firmly in place by the serving wire.

A pin 22 is mounted in a perforation in the spike just forward of the shoulder 23 therein, to prevent the insertion of the spike too far beneath the strand, said pin acting to prevent the strand slipping back on the reduced portion of the spike and becoming engaged in rear of said shoulder.

By reference to Fig. 2, it will be seen that the shank of the spike 14, having the reduced inner end 24, has mounted on said reduced portion, between the traveler head 10 and a shoulder on the shank, a washer 26. The washer 26 maybe removed and spike 14 adjusted to allow more space be tween the point of the spike and the hooks 2, which will admit a larger sized cable therebetween.

The operation of the device as above described is as follows:

The rope or cable to be spliced is unraveled the proper amount to supply the free ends of the strands for insertion in the rope or cable to which it is to be spliced. The usual serving wires or cords 21 are bound tightly around the cables to prevent furtherv unraveling of the strands. One of the cables is then placed in the hooks as shown and the crank is operated to bring the point of the marline spike beneath the strand to be lifted, as clearly illustrated in Fig. 1. When said strand has been lifted and the strand passed beneath it, the spike is withdrawn, the cable turnedover to bring another strand into the proper position and the operation repeated. After the splice has been completed, the serving wires are removed.

It will be understood that the above operation is followed when the ends of two sections of cable or rope are to be spliced together. When a loop is to be formed in the end of a cable, the serving wire is necessary at one point only.

Having thus fully described my invention, what I claim is 1. A device of the class described having side members terminating in hoo {S to receive a cable, a cross head at their opposite ends, and a guide brace intermediate their ends, a traveler block mounted to slide between the cross head and the guide brace, a spike mounted for slidable movement in the guide brace and secured to the traveler block, and a screw-threaded shank mounted at one end 3. A device of the class described, consisting of parallel side braces terminating at one-end in hooks adapted to receive a cable, a cross head at their opposite ends connecting same, an intermediate guide brace connecting the same, a traveler block slidably mounted on the braces between the cross head and the guide brace, a spike adapted to be inserted beneath a strand of the cable mounted in the guide brace and secured to the traveler block, a screwthreaded shank mounted in the guide brace and the cross head for rotary movement and operating in a screw-threaded aperture in the traveler block and adapted to receive acrank at its outer end, and means for securing the cable in the hooks when spike is withdrawn.

4:. A device of the class described having side members terminating in books to receive a cable, a cross head at their opposite ends, and a guide brace between the side' members, a traveler block mounted 'to slide between the cross head and the guide brace, a spike mounted for slidable movement in the guide brace and secured to the traveler block, a screw-threaded shank mounted at one end in the guide brace and at its other end in the cross head and adapted to operate the traveler block, and means for adjusting the spike in the traveler block.

This specification signed and witnessed this 9th day of October A. D. 1916.
